Detonation product equation-of-state directly from the cylinder test
A quasi-analytic method is presented for obtaining the detonation-product expansion isentrope directly from cylinder test data. The idea actually dates to G.I. Taylor`s invention of the cylinder test--though he did not implement it for lack of data--but has received little attention since. The method uses the fact that the pressure may be determined from the measured wall trajectory, whereupon the associated specific volume follows from the equations of continuity and momentum. Using the HMX-based explosive PBX9501 as an example, the method makes a good prediction of the detonation pressure and the basic form of {gamma}, the isentropic exponent. However, the model isentrope is slightly low in the mid-range, perhaps because the standard cylinder test is not optimal for this analysis. A better-suited design is proposed, and a simple ad-hoc correction is offered that reconciles the standard test.
